Consider 100 planes sent out and only 50 came back, 30 with fuselage and 20 with engine damaged, 10 undamaged. The rest are shot down due to either of the damage, or both. Further assume that the probabilities of fuselage and engine damages are 0.7 and 0.4, respectively. What is the chance of survival under both damages? (8pt) Are engine and fuselage damage events independent? (2pt) please explain answers
